Is there a way for the Nav to display vehicle speed (like my portable GPS did)?

Also, is there a way that it can display miles/kms remaining based on fuel in the tank? My old truck used to be able to show at any time how many kms until empty. In my A5, it gives a warning when low on fuel and 50kms to empty, but thats about it.

 

on my A4 with the Premium trim I can get digital speed readout to display in the center MFD (between the tach and speedometer). Right below it, I can also get it to show distance to empty, instantaneous fuel efficiency, etc etc.

This is all controlled via your wiper stalk. There is a button at the bottom of the wiper stalk that switches between programmed screens on your MFD (Digital Speedo, Trip Computer A, Trip Computer B), and a toggle switch at the end of the stalk that lets you cycle the secondary readouts (Distance to empty, fuel efficiency, trip time, etc)
